    "abstract": "We discuss a simple search problem which can be pursued with different\nmethods, either on a classical or on a quantum basis. The system is represented\nby a chain of trapped ions. The ion to be searched is a member of that chain,\nconsists, however, of an isotopic species different to the others. It is shown\nthat the classical imaging may lead as fast to the final result as the quantum\nimaging. However, for the discussed case the quantum method gives more\nflexibility and higher precision when the number of ions considered in the\nchain is increasing. In addition, interferences are observable even when the\ndistances between the ions is smaller than half a wavelength of the incident\nlight.",
